Why is SBS 2011 stopping access to Ebay or Amazon?


I have recently installed SBS 2011 on our network. We have about 8 clients on the network but a problem with internet access has recently come to light.

We have an ebay and an Amazon account that we use for selling but I have recently had complaints from some of our people saying they cannot get access to Ebay or Amazon. The sites just do not work and the page simply says there is no internet connection but then go to a different site like Google and the internet works.

Is there some kind of default restrictions for these sites in SBS 2011?

Many thanks

No there isn't. SBS does not do any internet proxy or filtering. You'll need to do some troubleshooting. Things I'd look at:

1) When the problem is reported, is DNS working?
2) Do you use a DNS service that does blocking/filtering such as OpenDNS?
3) Do the pages work using another browser? (portable versions of firefox and chrome are great for this)
4) Does your edge router/firewall do URL filtering? Does it do logging so you can see results?
5) Use a tool like HTTPWatch to see if the browser is properly making requests (malware can alter URL requests on the fly)
6) Use a tool like wireshark to make sure traffic is leaving the affected system as expected.

Those would be my troubleshooting steps, in that order, in increasing complexity, to identify the problem.

Couldn;t do much testing at the office due to Easter Holidays but it turned out Amazon was down when I had the problem and I think Ebay was affected as well, so problem solved :)
